Finding sustainable and efficient ways to extract natural products is becoming increasingly important for both the pharmaceutical and food industries.In this study, we propose a target-oriented approach for the rational design of composite bio-derived solvents, specifically tailored for the simultaneous extraction of salvianolic acid B, tanshinone I, cryptotanshinone and tanshinone IIA from Salvia miltiorrhiza root.We systematically evaluated the extraction efficiency of various bio-derived solvents, including glycerol carbonate, ethylene glycol, levulinic acid, glycerolformal, Et lactate and γ-valerolactone, both individually and in combination.Using a mixture design integrated with statistical modeling and optimization algorithms, we identified that the composite solvent system of GF/LA (57.8/42.2, volume/volume) greatly improved the extraction of both hydrophilic and lipophilic compoundsThe extraction yields were significantly higher compared to those obtained using individual bio-derived or traditional solvents, while the overall solvent consumption was lower.Addnl., we explored the use of macroporous adsorption resins to recover the extracted compounds from GF/LA (57.8/42.2, volume/volume) extracts solution, achieving impressive recovery yields of over 80%.Our findings provide valuable insights into the sustainable extraction of bioactive compounds and suggest practical applications for both anal. and industrial-scale processes, aligning with green chem. principles.
